In a bizarre video released this week, American socialite Paris Hilton teamed up with the Israeli research center the Weizman Institute of Science to announce the creation of a super-condensed type of sparkling water called the Nanodrop.

The announcement turned out to be an early April Fool’s joke, the Jerusalem Post reported, and was actually created by the Israeli at-home soda machine company Sodastream as part of a new ad campaign.
